My invention relates to closures for receptacles. While considered specially adapted for use for tubes such as employed for toothpaste and shaving cream, it may be used in connection with 5 Various receptacles such, for instance, as are employed for face powder and other toilet preparations and medical preparations.

The object of the invention is to provide a closure which may be readily manipulated to cause 10 the'opening and closing of such receptacles, and which when manipulated into open position will still remain attached to the receptacle. For use with such receptacles, it is customary to provide screw caps which when unscrewed are entirely 15 free from the receptacles. When thus manipulated, the screw caps are frequently dropped which not only causes inconvenience, but the caps are sometimes irretrievably lost as by going down the outlet openings of wash bowls. All such in- 20 conveniences are obviated by the employment of my invention.

The novel features which I believe to be characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with additional objects and advantages thereof will be best understood from the following description of a specific embodiment when read in con- 30 nection with the accompanying drawing, in which Fig. 1 is an elevational view of a receptacle showing the closure thereon in closed position. Fig. 2 is an elevational view showing the closure unscrewed and ready to be turned over into open 35 position. Fig. 3 is a top plan View of the receptacle. Fig. 4 is an elevational view showing the receptacle before the cap is attached thereto. Fig. 5 is an elevational View of the cap or closure. Fig. 6 is a bottom plan view of the closure.

40 Fig. 7 is a View in central vertical section showing the cap in closed position on the receptacle. Fig. 8 is a View in central vertical section showing the cap in fully open position and attached to the receptacle.

V 45 Referring to the drawing, the numeral I designates a receptacle which may be either in the form of a collapsible tube now in general use or may be any receptacle suitable for having my invention applied thereto. The receptacle has a 50 neck member l2, the upper portion of which is provided with external screw threads I4. The upper edge of the neck member is for a portion of circumference cut away or notched as indicated at IS. The purpose of the notch is to in- 55 sure that the threads M will begin at the proper place for engagement with internal threads I8 formed in the closure 28. This closure is provided with a sealing disk 22 while the upper edge of the closure around its periphery is knurled as indicated at 24. The lower margin of the 010- sure on its exterior is provided with a one turn helical rib E6 the pitch of which is preferably the same as that of the threads l4 and I8. Adjacent the two spaced ends of the rib 26 and. extending above the same, the cap 29 is provided 10 with a notch 23 the purpose of which will shortly appear. The top of the container Iii adjacent the neck is provided with an attaching member having a base 39 from which a lug 32 extends in upright position spaced from the neck member 12 as shown in Fig. 4 before the cap is attached. The base 36 adjacent the lug 32 is provided with a groove 3 3. In order to attach the cap to the receptacle, the rib 2'6 is placed in the groove 34, and the lug 32 is bent down over the rib as shown in Fig. 8.

The operation and advantage of my invention will be readily understood in connection with the foregoing description and the accompanying drawing. Assuming that the cap is resting on the neck member E2 in the position shown in Fig. 2, the threads 14 and I8 are ready to begin their interengaging action. The notch l6 insures the proper place. Upon now turning the cap toward the left, it will be screwed down and brought to rest with the lower end of the rib 26 engaging the lug 32 as a stop as shown in Fig. 1. In order to open the receptacle, the turning movement of the cap is reversed until the upper end of the rib 26 engages the lug 32 35 as a stop in the manner shown in Fig. 2. The cap may now be swung back into the position shown in Fig. 8, the notch 28 providing clearance for the lug 32 so as to permit this action. The neck member !2 will now be fully exposed, but the cap cannot drop off the receptacle.

Although I have shown and described a certain specific embodiment of my invention, I am fully aware that other embodiments thereof are possible. My invention, therefore, is not to be 5 restricted except insofar as is necessitated by the prior art and by the spirit of the following claims.

I claim:

1. A closure for receptacles having a neck member comprising a cap having rotative engagement with said neck member, a helical one turn rib around said cap, and a lug carried by the receptacle in which said rib is held and is adapted to turn whereby said cap when removed from said neck member is kept attached to the receptacle.

2. A closure for receptacles having a neck member comprising a cap having rotative engagement with said neck member, a helical one turn rib around said cap, and a lug carried by the receptacle in which said rib is held and is adapted to turn whereby said cap when removed from said neck member is kept attached to the receptacle, said lug serving as a stop for the upper end of said rib when said cap is in open position and serving as a stop for the lower end of said rib when said cap is in closed position.

3. A closure for receptacles having a neck member comprising a cap having rotativev engagement with said neck member, a helical one turn rib around said cap, and a lug carried by the receptacle in which said rib is held and is adapted to turn whereby said cap when removed from said neck member is kept attached to the receptacle, said cap above the ends of said rib having a notch to provide clearance for said lug so that said cap may be swung away from said neck member.

s. A closure for receptacles having an externally screw threaded neck member comprising a cap having internal screw threads for cooperation with the screw threads of said neck member, a helical one turn rib around said cap, and a lug carried by the receptacle in which said rib is held and is adapted to turn whereby said cap when removed from said neck member is kept attached to the receptacle, said lug serving as a stop for the upper end of said rib when said cap is in unscrewed position and serving as a stop for the lower end of said rib when said cap is in closed position.

5. A closure for receptacles having an externally screw threaded neck member comprising a cap having internal screw threads for cooperation with the screw threads of said neck member, a helical one turn rib around said cap, and a lug carried by the receptacle, said lug when in up standing position with said rib adjacent thereto being bent over whereby said rib is held and is adapted to turn therein and whereby said cap when removed from said neck member is kept attached to the receptacle.

6. A closure for receptacles having an externally screw threaded neck member comprising a cap having internal screw threads for cooperation with the screw threads of saidneck member, a helical one turn rib around said cap, and a lug carried by the receptacle in which said rib is held and is'adapted to turn whereby said cap when removed from said neck member is kept attached to the, receptacle, said cap above the ends of said rib having a notch to provide'clearance for said lug so that said cap may be swung away from said neck member.
